Choosing and using diagnosis tools and controls on z/OS

Below is a description of the types of tools and controls you can use for diagnosing and managing problems in the product environment.

Before you begin

The product uses a variety of different tools and server controls to help you collect specific types of data to determine where your servers are encountering problems. To efficiently use these tools you need to be aware of the different functions each can provide and what type of information will be available from each.
New feature New feature: This topic references one or more of the application server log files. Beginning in WebSphere Application Server Version 8.0 you can configure the server to use the High Performance Extensible Logging (HPEL) log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files or native z/OS logging facilities. If you are using HPEL, you can access all of your log and trace information using the LogViewer command-line tool from your server profile bin directory. See the information about using HPEL to troubleshoot applications for more information on using HPEL.newfeat
